There is something seriously wrong with a mother who would decline increased child support and food for her children out of pride and spite.

In my book, that means she hates the two of you more than she loves her children.

I really hope your partner contacts his attorney. The current custody arrangement should be addressed. If she won't take assistance, the well being of the children is at risk and the time spent in your household should be increased.

NTA. Not one bit.

I wish someone like you would cook for me! I hate cooking but end up having to do the majority of it in my household.

I'm going to write a cookbook. It's going to be called "The Resentful Cook" and it will be filled with all my crappy recipes lol.

Good luck to you.
